Three-parameter optical fiber sensor based on a tilted fiber Bragg grating

Characterization of Graphene Oxide Coatings onto Optical Fibers for Sensing Applications

“…They were inscribed into the fiber core with a 248 nm KrF excimer laser, using the phase mask technique. More details about the TFBG technology and its production can be found in the literature [13,14].…”

“…The refractive indices were measured at 21 ºC, using an 8º TFBG based refractometer [14]. The tests were accomplished within a climatic chamber (Challenge Angelantoni Industrie, Model 340) at 21 ºC.…”

“…A progressive smoothing of the spectrum is obtained with the increasing of the RI, due to the cladding modes that becomes weakly guided within the fiber, reducing its resonance amplitude [14].…”

Design and Testing of a 2D Optical Fiber Sensor for Building Tilt Monitoring Based on Fiber Bragg Gratings

“…In recent years, optical fiber sensors made of silicon-based optical fibers or polymer optical fibers have been commonly utilized for numerous types of physical detection [1][2][3][4][5][6][7][8][9][10][11][12] because a fiber sensor has many features that are better than conventional electronic sensors. Fiber optic sensors can be used for large-scale distributed monitoring, and also have anti-electromagnetic interference, high sensitivity, light weight, good adaptability in shape, and electrical isolation.…”

Cost effective refractive index sensor based on optical fiber micro cavities produced by the catastrophic fuse effect

“…To overcome such limitations, new types of optical fiber based refractometers have been the focus of extensive research over the last years. Several optical fiber refractometers based on Bragg gratings in etched optical fibers [5], long period gratings [6], tilted Bragg gratings [7] and surface plasmon resonance [8] have been reported.…”
